To all whom it may concern.; I y

Be it. known that I, Amon F. Towne, citizen Vof tite United States, residing at Colorado Springs-in the county of El Paso and St te of Colorado, have invented een tain new and useful improvements in -EX- piosive-Engines, of which the following is a specification.

This invention relates to improvements in explosive engines, preferably of the .two c cle type, though there aregfeatures probaiy useful in engines having` lciieren; cycles of movement.

The .primary object of the present invention is to provide novel, simple fnd pra@ ticable means, l,whereby the crceomenating from the explosions 'operates against oppositely movable heads, thereby securing a de- Cded increase in power and c better nal-v 'anceci engine, seid means being so constructl ed that the engine is very compact, and ports that are movable into and out of register 'take the place of the ordinary valve mechanism, the arrangement of saiol` ports being exceedingly simple. n j

yThe refereed embodiment of the inven-l tion is i luetrated in the accompanying drawm ings, wherein Figure 1- is a sectional view through the engine, showing the cylinder, partially in elevation. Fig. 2 is a sectional View at ri ht angles to Fig. jt. Fig. 8 is e' side elevation of a portion of the casing, and Eig. 4 is a sectional View on the line e-i of Fig. E.

Similar reference numerals designate co1'- responding parte in all the iig-ores of the drawings.

In the lembodiment discloseii, a casing is employed, which comprisesv 'a tubular guide 5, preferably. Water-jacketed, as shown at 6, and an enlaifged crank case located at one end of thegilde, said guide having opposite portions S that project into tlie crank case and are spaced apart, forming slots 82 The crank com is preferably formedof sections 9 and 10 bolted together, as shown at. li, the

section 9 `being integral with the. tubular guide 8, and tlie section ,l having a removable bottom 123; reciprocatory cylinder 13 operates in the tabular guide, and has an' o en that. is: itl communication with the 1n rior of .the orfani;case., said interior condei'. Anfenghe sliat 16,l journaiecl iii enitabl'e bearings l? in voiie opposite siiee ci they crank cese,l.ias oppositeiy disposed cranks 18 and it) located in the crank case. The cylinder 13 is 'provided with outstanding ears Q0 that reciprocate in the slots 8a, and pitnien 2l journaleol on pivot boite 2Q secured to the ears and cyiiniler, are connected to the cranks 18. Another pitnian 23, pivotally connected, as shown at 9i to the piston, is connecte@d to the opposite crank 19. In practice, the eylincier.l3 with its pitnien 2l 1s preferably of the same weight as the pisston l and its pitman 23, so that theseoppositely reciprocating parte will be balanced.

The charges 'of motive Huid 'are supplied to the compression 'chamber 14 from' any suitabie source throu h a pipe 25, and the extension 8 ci tl'ietnular guide 5, is provided with .a port 26 that communicates with said compression chamber. The cylinoleil 13 is also provided with a port 27 movable into and out of alinement with the port 26, said .port 27 registering with the port 26 when the cylinder is in `ite outermost position. The

exhaust takes placethrough an opposite port 2S formed inthe cylinder and movable into and. ont of register with a. port 29 'orme in the tubular guide opposite the 'port 26. An

nigniter 3l of any suitable structure is mounted on the heac' of the cylinder, and a.

contact element 32, located at one side of thel cylinder, has an electrical connection 33 with` the igniter. The Contact clement 32 is pre erabiy located in the upper end. of :in insu .loting strip 3e -`cai'iiecl by' one side of the.

cylinder. Another Contact element, in the form of a. head 35, is iovided With a Steur 36 mounted in, en insti ator 87, and said in enlator is cari'ie by a `bushing lyformed upon a supporting plete 39 that. is slidablyy mounted on one side of the case. The busl1- ing operates in a slot 40 formed 1n said case.

A springv 41, located in the insolatorbears Y' against the heed 35 Vto force the same in Warclly, 'and nuts 42, threaded upon the outer end :ofthe stem, serve to limit the distance .said liea may move inwardly. These nuts constitute parto'f :'11 binding `post, which in* ,clinics e' binding 43 for one of the electrical leads 44. The other lead 4.-.5 is gijoundi ed, as shown at 46 directly on the casing. A spring' 47, seated in one side of the case, bears downwardly against; the bushing 38,

in Y

velevated position, the piston will be in its and constitutes means for urging the same downwardly, anda bell crank lever i9, it'ulcrumed as shown at 50 on one side or' the case, has a pin and slot connection 5l with the supporting plate 39. The other arm of the lever constitutes a handle 52, and asuitable dog 53, Acarried thereby, cooperates with a holding rack 54, and has a plurality of notches 55 therein to receive the dog.

The operation of the structure is substantially as follows: Assuming the cylinder in lowermost position, in which ease, the ports 26 and 27 will be in alinement, and a previously compressed charge in the chamber 14 will pass through the said ports into the cylinder above the' piston.. Upon the down- Ward movement of the cylinder, the piston will move upwardly. Consequently the ports 26 and 27 will movelout of alinement, and -the piston l5, passing the port 27, will compress the charge in the cylinder. As the cylinder reaches the limit of its downward movement, the contact element 32 of the .igniter 31 Will engage the contact head 35,' and consequently, a circuit `will be closed, which includes the igniter. A spark will thereupon be formed, and a compressed charge exploded. The force' of this explosion will beagainst the headof the cylinder, and the piston. Consequently they will he moved in opposite directions until the port 28 of thel cylinder alines-with the exhaust port 29, whereupon the spent gases can escape. During the upward movement of the piston While the charge above described is being compressed, another charge will be drawn through the pipe 25 into the chamber 14, and as the piston kmoves downwardly under the force of the explosion, this charge will be compressed. Therefore while the cxhaust through ports QS and 29 isvtaking place, the said compressed charge will be admitted through the registering ports QG and 2T. Consequently the operation will be repeated, as will be evident. The timing of the explosion can bereadily altered by operating the handle 52 of the lever 49, whichI as will be evident, will cause the contact head 25 to be moved to different positions with iespect to the contact element 3Q. Moreover the contact head 35 has a movement sufficient to carry it to a position sothat it will not be engaged by the element 3Q. in order that the explosions may be prevented it desired. lith this structure therefore. it will be evident that a simple and practicablcfengine is provided which will develop a -greater amount of power than an Iengine having a stationary cvlindqr. and said engine furthermore is balanced so that vibration materiallv reduced,

From the foregoing. it is thought that the construction. operation and many advan, tages of the herein described invention w1ll i eoaasa be apparent to those skilled in the art without turther description, and it will be understood that various changes in the size, shape, proportion, and minor details ot construction, may be resorted to lwithout departing from the spirit or sacrificing any o' the advantages ot' the invention. JFor instance, in the present embodiment, a single cylinder is shown, but it will be understood that engines may be constructed with` as many cylinders as desired.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
